Preparation technology of energy storage materials

What are the types of energy storage materials?

The types of energy storage materials are mainly divided into sensible heat storage materials, latent heat storage materials and chemical heat storage materials [12, 13]. Latent heat storage materials are used to store/release heat energy by using the endothermic/exothermic energy conversion method when the PCM undergoes a phase change .

What is heat storage technology?

Heat storage technology is an effective way to alleviate the time and space conversion of heat energy and the mismatch between supply and demand, and improve energy utilization. The core and key of TES is energy storage materials.

What is thermal energy storage?

Among them, thermal energy accounts for more than 70% of global energy consumption and is the primary form of energy for industrial applications and daily life. Thermal energy storage can be broadly classified into sensible heat storage and latent heat storage (i.e., phase change energy storage).

How to improve energy storage mechanism in electrochemical devices?

In order to enhance the energy storage mechanism in electrochemical devices, some materials, because of their unique 2D structure, act on electrode materials or electrolytes, can improve the storage of ions and the speed of embedding and exiting, and accelerate the rapid transfer of ions in the electrolyte.

Are phase change materials suitable for thermal management?

With the increasing demand for thermal management, phase change materials (PCMs) have garnered widespread attention due to their unique advantages in energy storage and temperature regulation. However, traditional PCMs present challenges in modification, with commonly used physical methods facing stability and compatibility issues.

What are thermochemical heat storage materials?

Thermochemical heat storage materials are based on the storage/release of heat energy during a chemical reversible reaction. Thermochemical reaction has the largest energy storage density among the three methods while chemical reaction has certain safety risk and may cause environmental pollution .
